Deep hole drilling RT Gun drilling operations must utilize a pilot hole or guide bushing for successful Aluminum and other non-ferrous metals.

designed for deep hole drilling in virtually any material, can be Aluminum. Iron. ▫. Solid Carbide Twist Drills. Deep Hole Twist Drills are available 

Deep Hole Drilling – Top Seiko Produces Deep, Straight / Tapered Holes in Ultra-Hard Alumina, Aluminum Nitride, Fused Silica Glass, Borosilicate Glass, 

Gun drilling can be done, with limited performance, on common CNC machines. Holes with a depth-to-diameter ratio of 20:1 or greater generally require dedicated equipment to achieve the highest productivity and process reliability, and can reach extreme ratios of 400:1 or greater. Gun Drilling vs BTA Drilling

The main difference between drilling aluminum and harder materials, noted Jason Hout, global DHM (deep hole machining) product and 

We are trepanning a 21" ID (inside diameter) in this piece of 25" OD x 61" long piece of 6061 aluminum. This process also retrieves a core approx. 19.5" solid round. At Trepanning Specialties we can gundrill, BTA and trepan from .125" to 21" ID's in all kinds of material. Utilizing trepanning, gun drilling, BTA Systems, and boring

Stegman Tool can hold a tolerance of +/-.0005 straightness per inch with our anti-rotation attachment, which is a tighter tolerance than the industry standard. Materials drilled are carbon steel, stainless steel, Inconel/Nickel based alloys, aluminum, coppers, and many more. [table id=5 responsive=flip /]

Gundrilling is a highly flexible, efficient and quick method of producing deep or shallow holes. Producing close-tolerance holes with smooth surface finishes, usually in one pass. This often eliminates the need for reaming, honing, or other finishing operations. Less known are the potential advantages of shallow hole and deep hole gundrilling.

For a diameter-length-ratio from 15xD one generally refers to gun drilling. Gun drills are for example applied for the machining of camshafts, crankshafts,

Gundrilling Advantages Building our expertise since the 1970's, Carlson has drilled practically every metal alloy in all industries. The gundrilling process offers a few key advantages including much smaller hole sizes (2.0″ down to 0.055″), more parts to production hour, tight tolerances and more.
